This name had previously been “lectotypified” by Mártonfi in 1997 from a specimen kept at the herbarium LINN (Herb. Linnaeus No. 38.6). However, Linnaeus cited a specimen of Sauvages in the protologue, currently preserved in the herbarium LINN (Herb. Linnaeus No. 38.5). Therefore, in lectotype desig- nation this specimen must be chosen according to the International Code of Nomenclature for algae, fungi, and plants (Art. 9.12 of the Shenzhen Code of 2018). Key words: Labiatae; lectotype; Linnaeus; nomenclature; syntype. Resumen TIPIFICACIÓN EFECTIVA DEL NOMBRE LINNEANO THYMUS PULEGIOIDES (LAMIACEAE).— Se revisa la tipificación del nombre de Linneo Thymus pulegioides (Lamiaceae). Este nombre fue previamente “lectotipificado” orp Mártonfi en 1997 a partir de un espécimen conservado en el herbario LINN (Herb. Linnaeus No. 38.6). Sin embargo, Linneo citó un espécimen de Sauvages en el protólogo, en la actualidad conservado en LINN (Herb. Linnaeus No. 38.5). Por lo tanto, en la desig- nación del lectotipo debe elegirse este espécimen de acuerdo con el Código Internacional de Nomenclatura para algas, hongos y plantas (Art. 9.12 del Código de Shenzhen de 2018). Palabras clave: Labiatae; lectotipo; Linneo; nomenclatura; sintipo. Cómo citar este artículo / Citation Ferrer-Gallego, P. P. 2020.
